climate
Grows in humid, mountainous, tropical regions in partial shade, can also be
grown as a houseplant in temperate regions.
soil
Grows best in soil that is neither too dry nor susceptible to flooding,
prefers moist, well-drained and rich in organic matter.
growing
Plant peppercorn seeds indoors 1/2" deep. For proper germination keep seeds
damp and remain at 50% humidity or higher and 75 to 85°F.
After seeds have germinated, keep soil moist and from drying out. Transplant
in larger pots as seedling grows.
harvesting
Black pepper is produced from the still-green unripe drupes of the pepper
plant. The drupes are cooked briefly in hot water, both to clean them and to
prepare them for drying. Heating in hot water ruptures cell walls in the pepper,
and speeds the work of browning enzymes during drying. The drupes are dried in
the sun or by machine for several days, during which the pepper around the
seed shrinks and darkens into a thin, wrinkled black layer. Once dried, the
spice is called black peppercorn.
White pepper consists of the seed of the pepper plant alone, with the
darker-colored skin of the pepper fruit removed. This is usually
accomplished by a process known as retting, where fully ripe red pepper
berries are soaked in water for about a week, during which the flesh of the
pepper softens and decomposes. Rubbing then removes what remains of the
fruit, and the naked seed is dried.
Green pepper, like black, is made from the unripe drupes. Dried green
peppercorns are treated in a way that retains the green color, such as
treatment with sulfur dioxide, canning or freeze-drying.
preserving
Store dried peppercorns in an airtight container in a cool, dry place.
